Defi Ether network ->> did I get ripped off??

I need help analyzing the legitimacy of a Defi network. The network is "Defi Oracle Meta Mainnet". https://chainlist.org/chain/138

Specifically the biggest red flag is the transactions on block 29 of this blockchain. I need to understand the details on how the minted 999,000,000 ETH transaction can be tied to real ETH.. or is this a 'worthless' ETH?.. I bought into this network and now I cannot get my money out or swap/bridged..
